About Kranz Lake Dam
The primary purpose of Kranz Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Wayne Kranz (private). It impounds the Graham Br Clear Fk Blackwtr R near Sweet Springs.
The dam stands 33 feet tall, creates a reservoir covering 14 acres, has a maximum storage capacity of 247 acre-feet, and collects water from a drainage area of 39 square miles. Completed in 1972, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream.
At 33 feet, this dam is taller than 78% of dams nationwide.
